Begin by cooking ground beef in a large skillet over medium heat with the packet of French onion seasoning mix. Cook until the meat is fully browned and then carefully drain off any grease.

Remove the ground beef from the heat and set it aside to cool for a few minutes. While the beef is cooling, prep your slider buns.

Use a sharp serrated knife and cut the entire loaf evenly in a horizontal cut. Keep the buns connected. This gives you one large top bun and one large bottom bun. Repeat on the second loaf and set aside.

Prep 2 sheets of overlapping foil and spray with non-stick spray.

Once the beef mixture has cooled slightly, add the shredded cheese and the mayo and use a spatula to fully mix and combine everything.

Place your bottom buns over the foil so they are side by side and touching. Scoop all of your beef mixture and pour it evenly onto the bottom buns.

Add any other toppings like pickles, bacon, onions, etc as desired. Then cover with the slices of cheddar or American cheese.

Add the top buns and press down lightly. Wrap in foil tightly.

Bake or smoke the pull apart sliders in a preheat 350 F. degree oven (or smoker on indirect heat). Cook until heated through and the cheese has melted, about 25-30 minutes.

Melt the butter in a small bowl and brush over the top of the buns and then garnish with sesame seeds.

Place on a platter and allow your guests to grab and go as needed!
